| Abstract: |
An airfoil, pivotally attached to a high speed vehicle, is positioned to produce a braking action on the vehicle by means of fluid-dynamic resistance. The airfoil may be positioned to produce a downward pressure on the vehicle and thus enhance conventional braking action. The braking action is further augmented by eductors which reduce the air pressure behind the airfoil and control the air flow about the airfoil. The eductors and a set of rudders combine to provide the requisite stability for successful high speed braking.

I claim:
1. Apparatus for fluid-dynamic braking of a high speed vehicle comprising:
- (a) a wing member attached to said vehicle and positioned generally transversely across said vehicle,
- (b) an elevator attached to the rear portion of said wing member,
- (c) a rudder attached to said wing member and positioned generally in the vertically plane,
- (d) an eductor symmetrically positioned in said elevator surface,
- (e) means for positioning the upper surface of said elevator surface at an angle in the range from 0° to 180° with respect to the upper surface of said wing member, and
- (f) means for positioning said wing at an obtuse angle to said vehicle.
